    Notes: Summary. A multicentre trial was conducted to compare the efficacy and side-effects of an intramuscularly administered PGE2 analogue and vacuum aspiration in women with a delay of up to 21 days in the expected onset of menses. A total of 473 such women were randomly allocated to treatment with either 16-phenoxy-W-17, 18, 19, 20-tetranor PGE2 methyl sulfonylamide (three intramuscular injections of 0.5 mg at 3-h intervals) or vacuum aspiration, and the outcome of therapy assessed 1, 2 and 6–8 weeks later. Retrospective analysis of hCG levels indicated that 419 (88.6%) women had been pregnant at the time of treatment. With few exceptions, administration of the PGE2 analogue induced vaginal bleeding in both pregnant and non-pregnant women but the duration and subjectively perceived amount of bleeding were greater than after vacuum aspiration. Both treatments were equally effective. In pregnant women the overall frequency of complete abortion was 91% for prostaglandin treatment and 94% for vacuum aspiration. If non-pregnant women were included, the respective success rates (i.e. percentages of women not pregnant 2 weeks after treatment) were 92% and 95%. Gastrointestinal side-effects and lower abdominal pain requiring intramuscular analgesia were more common after prostaglandin therapy than following vacuum aspiration in both pregnant and non-pregnant women.

    Notes: Abstract A low molecular weight, native zinc binding, cytosolic protein (LMZP) has been isolated, purified and characterized from human normal term placenta. Gel filtration of heat treated placental cytosol after sequential acetone precipitation (80% ppt) revealed a major zinc binding protein in the range of low molecular weight. This partially purified zinc binding fraction was further fractionated on DEAE-Sephadex A-25. The zinc was eluted in one of the three peak fractions. Further, the purity of zinc binding protein was confirmed on fast protein liquid chromatography (FPLC). The purified placental LMZP was homogenous on SDS-polyacrylamide gel electrophoresis with a single band. Ultraviolet (UV) spectrum of LMZP showed an absorption maximum at 257 nm which disappeared at pH 2. Molecular weight of LMZP as determined by gel chromatography, SDS-polyacrylamide gel electrophoresis and amino acid analysis was 6 kDa. It was calculated that 1 g atom of zinc was bound to 1 mole of the LMZP. Unlike in classical metallothionein, the amino acid composition of placental LMZP revealed the presence of aromatic amino acids, lower content of cysteine and higher content of histidine, glutamic acid and aspartic acid (10, 9 and 5 residues/mole, respectively).

    Description / Table of Contents: Resumé Vingt-cinq femmes utilisant un contraceptif contenant du lévonorgestrel, le Norplant-2, ont fait l'objet d'une étude longitudinale visant à déceler les effects de l'utilisation de ce contraceptif sur le profil des lipides, la tolérance au glucose et les transaminases hépatiques, à court terme (12 semaines) et à long terme (18 à 24 mois). On a évalué les lipides totaux, le cholestérol, les phospholipides, les triglycérides et leurs sous-fractions. On a constaté une augmentation significative du LDL cholestérol après 12 semaines d'utilisation (p〈0,05), qui n'existait plus lors des visites de suivi 18 et 24 mois plus tard. Le HDL cholestérol, le rapport entre les HDL et LDL cholestérol, les phospholipides, les autres fractions lipidiques, les transaminases hépatiques et la tolérance au glucose n'ont pas été significativement modifiés par l'utilisation à court ou à long terme du Norplant-2.
    Abstract: Resumen Veinticinco mujeres que utilizaban un anticonceptivo que contenía levonorgestrel, el Norplant-2, fuerón objeto de un estudio longitudinal a los efectos de determinar el perfil de lípidos, la tolerancia a la glucosa y las transaminasas hepáticas en el uso a corto plazo (12 semanas) y a largo plazo (18 a 24 meses). Se evaluaron los lípidos totales, el colesterol, los fosfolípidos, los triglicéridos y sus subfracciones. Se verificó un aumento significativo de LDL colesterol tras 12 semanas de utilización (p〈0,05), que no persistió en las visitas al cabo de 18 y 24 meses de utilización. El HDL colesterol, la relación entre los HDL y LDL colesterol, los fosfolípidos, las otras fracciones de lípidos, las transaminasas hepáticas y la tolerancia a la glucosa no fueron modificados significativamente por la utilización a corto o a largo plazo del Norplant-2.
    Notes: Abstract Twenty-five women using levonorgestrel containing the contraceptive implant, NorplantR-2 were studied longitudinally, to see the effects on lipid profile, glucose tolerance and hepatic transaminases with short-term (12 weeks) and long-term (18 to 24 months) use of Norplant-2. Total lipids, cholesterol, phospholipids, triglycerides and their subfractions were evaluated. There was a significant increase in LDL-cholesterol after 12 weeks of use (p〈0.05), which did not persist at 18–24 months follow-up. The HDL-cholesterol, HDL/LDL-cholesterol ratio, phospholipids, other lipid fractions, hepatic transaminases and glucose tolerance did not alter significantly following short-term or long-term use of Norplant-2.
